Problems with Dock

[m82palmer]

About 3 weeks ago my system went mad.

The Dock stopped coming out of hiding or if it did magnification did not work.


The top level menus also semi stopped. When i clicked on a header it opened the menu, however if there was an expand arrow (like Dock or Location from the apple button) it would not expand if i hovered my mouse over it. If i clicked it, it would exit the menu.

So i restored my it back to factory settings. All is fine for a few weeks, an now it has happened again.

I have tried running Cocktail, Running Verify Disk Permissions and Disk, I have also tried "Sudo killall dock"

Any ideas? or should i just restore it again?


Edit

Expose also has stoped working


Edit 2

When i drag a file over the dock (as if i was going to put it in the bin) it works fine :S

When i click on the top menu, if i hold down the left mouse button, it all works.

Could it be a problem with the Mouse settings?



Edit 3

When i enable Mouse Keys in universal access everything works fine, which leads me to belive the problem is with the mouse. I have tryed a different mouse though and still the same :S
